The broader impact of this Small Business Innovation Research (SBIR) Phase I project is to greatly advance perovskite solar cells (PVSCs) in terms of efficiency, stability, and readiness for commercialization. The success of the proposed research and development (R&D) activities will ensure a smooth transition from the realization of concepts in Phase I to prototype development of PVSCs on flexible substrates through slot-die coating in SBIR Phase II. Our final products will be mass-produced through low-cost roll-to-roll (R2R) printing and satisfy the customer needs for additional and cheaper electricity. By integrating our high-performance fully flexible solar panels with freight trailers/reefers, freight-truck owners can significantly reduce the diesel fuel consumption (by 30%) and avoid idle run of diesel engine while the drivers are resting. When our products are attached to the military tents, sufficient electricity can be generated to meet electricity needs at forward operating bases (FOBs), thereby significantly relieving the demand for diesel fuel at remote locations and effectively limiting the casualties related to the fuel transportation. In addition to its technical and commercial contribution, this project will impact society by involving and educating the new generation on the PVSCs with a sub-award to The University of Alabama.The proposed project will clear the obstacles that currently preventing PVSCs from upscaling manufacture and commercialization. Metal oxides rather than organic materials as charge transport layers have been demonstrated to enhance both device performance and stability. However, high quality metal-oxide films require high thermal annealing temperatures and long annealing time, which will destroy both flexible substrates and perovskite absorber layer. Photonic irradiation will be employed to achieve rapid and layer-specific annealing for both metal-oxide hole transport layer (HTL) and metal-oxide electron transport layer (ETL) without damaging other layers in PVSCs. Moreover, the rapid layer-specific photonic annealing happens in seconds, which is fully compatible with the R2R printing. With compositional engineering, the perovskite absorber layer will also go through rapid photonic treatment. The resulted PVSCs will be able to achieve PCE over 25% with long-term stability and pave the way for large-scale manufacturing of PVSCs through high-speed printing. The proposed highly-selective photonic treatment for each stacking layer in HTL/Perovskite/ETL sandwich structure provides the solution to achieve stabilized PVSCs with efficiency over 25%.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究 (SBIR) 第一阶段项目的更广泛影响是在效率、稳定性和商业化准备方面极大地提高钙钛矿太阳能电池 (PVSC)。拟议的研发（R＆D）活动的成功将确保从第一阶段概念的实现顺利过渡到SBIR第二阶段通过狭缝模具涂层在柔性基板上开发PVSC原型。我们的最终产品将通过低成本卷对卷（R2R）印刷进行批量生产，并满足客户对额外且更便宜的电力的需求。通过将我们的高性能全柔性太阳能电池板与货运拖车/冷藏车集成，货运卡车车主可以显着降低柴油消耗（减少 30%），并避免驾驶员休息时柴油发动机空转。当我们的产品安装在军用帐篷上时，可以产生足够的电力来满足前沿作战基地（FOB）的电力需求，从而大大缓解偏远地区的柴油需求，有效限制燃料运输造成的人员伤亡。除了其技术和商业贡献外，该项目还将通过让新一代光伏太阳能电池参与和教育来影响社会，并将向阿拉巴马大学颁发子奖。该项目将清除目前阻碍光伏太阳能电池升级制造和推广的障碍。商业化。金属氧化物而不是有机材料作为电荷传输层已被证明可以增强器件性能和稳定性。然而，高质量的金属氧化物薄膜需要较高的热退火温度和较长的退火时间，这会破坏柔性基板和钙钛矿吸收层。 将采用光子辐照来实现金属氧化物空穴传输层（HTL）和金属氧化物电子传输层（ETL）的快速和层特异性退火，而不会损坏PVSC中的其他层。此外，快速的特定层光子退火在几秒钟内发生，这与R2R打印完全兼容。通过成分工程，钙钛矿吸收层也将经过快速光子处理。由此产生的PVSC将能够实现25%以上的PCE且长期稳定，为通过高速打印大规模制造PVSC铺平道路。所提出的对 HTL/钙钛矿/ETL 夹层结构中每个堆叠层进行高度选择性光子处理的解决方案，提供了实现效率超过 25% 的稳定 PVSC 的解决方案。该奖项反映了 NSF 的法定使命，并通过使用基金会的评估进行评估，认为值得支持。智力价值和更广泛的影响审查标准。
